SKF SPHER ROLLER BEARING 23036 CCK/C4W33

Spherical roller bearings consist of two symmetrical rows of rollers, a common spherical outer ring, and two inner rings that are angled relative to the bearing axis. The center of the sphere in the outer ring’s raceway lies on the bearing axis.

Spherical roller bearings are designed to withstand heavy loads while providing natural self-alignment. Unlike standard bearings, they automatically compensate for shaft misalignment, significantly reducing internal stresses. This SKF model, featuring an open design, is equipped with a 1:12 tapered bore, two pressed-steel cages, a shoulderless inner ring, and a floating guide ring centered on the inner ring. It is also designed with an annular groove and three lubrication holes on the outer ring.

Features:
This double-row roller bearing features a 1:12 tapered bore, allowing for precise mounting on a shaft or sleeve and also facilitating the adjustment of internal clearance. Its design incorporates two stamped steel window cages, a shoulderless inner ring, and a floating guide ring. These components ensure efficient roller guidance, reduce internal friction, and promote even load distribution, even in the event of misalignment or high loads. The C4 internal radial clearance improves tolerance to temperature variations and reduces friction. This results in smooth operation, even at high speeds. The inclusion of an annular groove and three lubrication holes ensures optimal lubricant distribution.

Maintenance:
This bearing is not pre-lubricated. It therefore requires regular relubrication to ensure consistent performance. The use of a high-quality lubricant, suitable for high loads and extreme temperatures, is strongly recommended. The operating temperature range can reach 200 °C, provided the selected lubricant is compatible. When operating in a dusty environment, prior cleaning of the contact areas is essential. It is also recommended to regularly inspect the bearing for contaminants or signs of premature wear. Paying close attention to relubrication intervals significantly extends the product’s service life.

Sealing:
This bearing is of the open type, meaning it does not have built-in seals. This design facilitates visual inspection and maintenance operations. However, it makes it more susceptible to external contaminants such as dust, moisture, or solid particles. To mitigate this vulnerability, the design includes an annular groove and lubrication ports that allow contaminants to be flushed out during relubrication. It is therefore crucial to ensure a clean and controlled operating environment, particularly during installation or maintenance.
